The St. Mark Clue

The St. Mark Clue
Reconstructing a night
Spade asks the hotel clerk about Brigid’s registration, movements, and visitors, learning that she checked out and left a forwarding address in Los Angeles.
A wider trail
The inquiry confirms that she has moved quickly and used incomplete identities, giving Spade a route to pursue without making her history trustworthy.
The Tail Identified

The Tail Identified
A persistent follower
A youth in a grey cap shadows Spade from street to theatre, then returns to watch his apartment building.
A second network
Spade recognizes the tail as connected to the larger contest and confronts him at Hotel Belvedere. The boy’s threats make the investigation physically dangerous.
A Search for the Bird

A Search for the Bird
No object found
Spade searches Brigid’s apartment thoroughly but finds no falcon, only jewelry and the signs of a recently occupied room.
A question of concealment
His failure to find the bird does not establish that she lacks it. The search instead shows how difficult it is to distinguish an empty room from a deliberate hiding place.
The Harbor Newspaper

The Harbor Newspaper
A torn arrival notice
Spade finds a torn section of the shipping news in Joel Cairo’s wastebasket and reconstructs the listing for La Paloma from Hong Kong.
A practical deduction
The ship’s arrival redirects his attention from vague criminal histories to the harbor. A small scrap of paper supplies a lead more reliable than the competing stories.
The Office’s Last Visitor

The Office’s Last Visitor
A dying messenger
Captain Jacobi reaches Spade’s office with the parcel and collapses before he can explain its route or the attack against him.
The harbor case converges
The harbor investigation ends at Spade’s desk, where the falcon’s delivery, a fresh death, and the danger of police discovery meet in one scene.
